I always love the laminar flow of the Tesla turbine . 10 years of age I was using the hose to clean out a Paint roller and found that I could get it spinning at great speed just by squeezing the end of the hose to create more pressure and I've been fascinated by the concept and of course people have been building wonderful little Tesla turbines and as much as it's not the answer to all things it certainly has its place that is just not being really utilised micro energy. Storage as every time you turn your tap on on your house or have a shower that could pressurise air first spin up a Tesla turbine for a period of time and stole the energy into batteries that could use for nighttime lighting in a house so Justin the water supply that is pressurised we lose all the energy by not taking advantage of it when we open the faucet in the Home and in fact in the 1940s or somewhere near there they did actually have these little dynamos. I think in England that used to create, a small amount of electricity for whatever use they had then
Great Jeremiah! Thank you for sharing your progress. One very intriguing application for the tech, aside from the whole our-of-the-grid home thing, is as an addition to a ICE water cooling system for hybrids, to recharge the car batteries not only with the mechanical power of the rotating shaft, while the ICE is running, but also with the most of the heat which usually is wasted away (about 60-70% of the total energy) through the radiators.
You may even open up another branch of physics at these speeds. Next, you can approach 10 percent the speed of light. Use this as a rocket to explore the stars. Keep up the amazing work.
You have water jetting. (Take the issue of compressed air when there is a pressure drop results in a lowering of the temperature (Measure that water temp over time) IF even condensation hits expanding air you stand a chance of ice forming somewhere in the system that then breaks off and collides with the turbine. It doesn't take much to destroy the balance in the turbine.
Thank you for the comment! You raise a very valid point. The issue of temperature drop due to the expansion of compressed air is indeed a critical factor to consider in such systems. As the air expands, the temperature can drop significantly, potentially leading to condensation and even ice formation, depending on the humidity level and temperature conditions. I've only encountered this issue under specific circumstances, such as when a strong vacuum was created by a pump stage attached to the same shaft, running both compressed air and water vapor inside the turbine. This could potentially be mitigated by using higher temperatures for the air. However, this system isn't designed for compressed air. If you check out my previous videos, you'll see that I use the Rankine cycle, and I haven't had any issues like those you're describing. The scenario could change if I were to use a powerful enough pump to decrease back pressure and increase the expansion ratio. But even then, since the turbine operates under vacuum conditions, the likelihood of ice formation remains low. Additionally, even if ice were to build up on the disks, it would be unlikely to cause damage. Unlike conventional turbines, which have buckets, paddles, or vanes that could be impacted at high speed, the Tesla turbine’s design minimizes this risk. Thanks again for your input, and please keep sharing your insights. It's always great to discuss these technical nuances with the community!
225w under load x 24 hrs is barely 5.5kwh @ 30v x 7.5a per hr if it could run for an hr lol, i love the idea of this tech i just realllly hope it scales as well as i think it should. not hating but if you want anyone to take you serious slap a gear system on this and attach a damn 5kw axial flux alternator and get hella watts per hour or die trying lol, this with a 22kwh per day output could power a house with solar heating in alot of places. dope build keep it up i hope something like this replaces reactors one day.
Check out my previous video: that was a polycarbonate turbine, so I couldn't let it get too hot. I've managed to generate over 2 kW with it. My new turbine, however, features an aluminum housing and titanium disks, and it's capable of much more. It can easily exceed 5 kW and has the potential to reach 40 horsepower if operated at high enough pressure and temperature-assuming the shaft can handle the torque without twisting off.
You should get an inlet needle valve for higher levels of control. That way you could ramp it up and see how much flow you need to start it spinning at certain loads, if that's something you care about.
Did you do that with a Tesla turbine? If so, consider using a larger inlet and increasing gas flow. That way, there won’t be too much friction slowing down the vortex at the periphery of the casing, where the rotor tips are closest to the sidewall. With small nozzles, you will have much thinner boundary layers, so pointing the nozzle away from the sidewall, as you described, helps.
You’re an inspiration Jermiah. I watched one of your previous videos with a heat source and a condenser at vacuum. Couple years later watching another video on desalinization I realized that is the cheapest form. Basically using horizontal black pipe on the desert sand , A reverse P-trap leading into a T, One end of the T goes into a vacuum pump which could be a tesla turbine maybe and the other end goes back under the ocean to condense the freshwater as it boils around 30° C. Another pump to pump the fresh water in the holding tank on shore. Once the dissolved gases boil off first then close the vacuum valve and we should have a self-sustaining vacuum with boil and condensation.
Another way to do it is by using the temperature difference between the ocean's surface and below. Either method would work. You would likely also want a different working fluid or gas that boils at lower temperatures due to the small temperature delta.
@@iEnergySupply yeah that’s what you’re doing to make power which is awesome but this is for freshwater. Makai Ocean engineering Did a test Plant at the natural energy laboratory of Hawaii doing what you suggest. They have a net gain and they’re making power.

The Denser your working fluid is, the greater the energy that will be transferred to the disks. Increasing Disk mass and diameter will yield greater torque. Greater torque means lower speeds will yield greater power transfer from the working fluid. Think in terms of spiral tapering blades inside of a cone structure. Greater surface area yields greater torque and energy transfer. Interesting project!!
Thanks for the feedback! We've actually built and tested the 6" rotor with great success. Contrary to your point, we've found that higher speeds actually mean more power with less torque, although the torque is still quite substantial. The turbine achieves its greatest power output when the rotor is moving at half the speed of the working fluid. In a vacuum, the steam velocity is extremely high, which makes it feasible to extract energy at very high peripheral velocities. We've also designed and built an efficient high-speed dynamo that works exceptionally well with this setup, allowing us to achieve extraordinary power output. The combination of high speed, vacuum conditions, and our dynamo design really pushes the efficiency to the next level. Thanks again for the interest-exciting times ahead with this project! Let me know what you think.
Reading his replies to people really gives a glimpse of what a special person he is. Patient, eloquent, understanding, and generous in his efforts into attempting to bridge gaps with people. His heart shines through brightly in all his actions i have seen. It’s cool too see his family showing support.
That’s why there’s a blast shield around it. A magnet exploded during a previous test at 99,800 RPM, but I was protected. In the future, we can reinforce it with carbon fiber or Kevlar wrapped in epoxy to make it stronger.
@@iEnergySupply actually i agree with him, the Plexiglas is not thick enough i would want double to be sure, at least use another shield in front of the one you have, the perimeter of that disc is probably going close to 500m/s thats close to bullet speeds.
@@ChrisDay-sx4lv Thanks for sharing your thoughts on this! To clarify, I’m using polycarbonate (Lexan) rather than Plexiglas for the blast shield. Lexan is significantly more resilient and is commonly used in ballistic protection due to its excellent impact resistance and energy absorption. For context, I once shot a 0.5-inch Lexan sheet with a .22 rifle, and it penetrated only about 0.25 inches. Given the high speed and mass of the lead bullet, this performance is impressive. The turbine casing is made from 3/4-inch Lexan, totaling 1.25 inches in thickness, which is more than sufficient to contain any potential debris from an explosive failure. For those considering replicating this blast shield, the method of joining the Lexan panels is crucial. Strong, secure joins are essential to ensure that the structure remains intact, as poorly bonded seams could be vulnerable to shrapnel. Additionally, the turbine’s discs are made from lightweight carbon fiber. While the periphery speeds are extreme, carbon fiber is much lighter than hardened steel or stainless steel, meaning it carries significantly less kinetic energy upon failure. This reduces the overall risk, but safety always comes first-so ensuring proper construction is key to a safe setup.
@@iEnergySupply you covered all the points I was going to make, Lexan really is tough stuff, hopefully its glued as well as screwed, the rear side of the turbine is exposed and you are working close to it, you should at least have something so a ricochet doesn't pose a threat. keep up the good work workmanship looks exceptional, Hope you release some efficiency data soon.
I suggest using Current Clamp for the Amps so you're not limited to 10A. You can get normal DC current clamp multimeter or get something more precise like PeakTech 4250 (20 or 60A) which has great value for the money and 4mm banana plugs for the multimeter. It's the same hardware as Pico TA018 but without BNC and shielding - which you can add yourself for cheap. Not to mention this hardware is mainly used with the oscilloscope so you have current frequency response up to 20 kHz. Looks like the project is getting further and better, keep up the good work!
I have a clamp-on ammeter, which I initially planned to use, but it wasn’t reading correctly. I later realized it was set to AC mode. Next time, I'll make sure to use it properly in the correct mode.
Love the sound of the turbine. such a unique sounds. thanks for showing us the tests. How long could you run it to say power a home or charge a large battery bank for later energy use?
If you saw the larger turbine before I tested the smaller one, that larger turbine is the one that can power your house. You just need to heat the thermal mass/battery to a suitable temperature.
It would be great to see a system that could take me off the grid here on the farm - I have PLENTY wood fuel for steam production. Keep up the good work - it will pay off.
This is exactly what you need if you have a good supply of wood! Stay tuned for updates, and consider joining my Patreon for exclusive insights on the turbine we're running on heat. Even free members receive updates occasionally.
Thank you for your comment! I completely agree-the potential for Tesla turbines in clean and efficient electric generation is huge, especially when combined with natural gas. Unlike traditional turbines, Tesla turbines can handle a variety of working fluids, and their unique design allows for efficient energy conversion with minimal mechanical wear. Integrating Tesla turbines with natural gas could provide a cleaner alternative to conventional power generation, as they can operate efficiently even at lower pressures and temperatures. This makes them ideal for distributed energy systems and microgrids, where they can be used for local power generation with lower emissions. We're continually exploring ways to optimize and scale this technology for practical applications in sustainable energy. Stay tuned for more updates as we push the boundaries of what's possible with this innovative design!
Not too hard, I have a system that runs constant now, just waiting for main valve control board. This was just a side experiment, the real stuff is on patreon and will soon come to TH-cam.
You're right, using low pressure water is safer than organic solvents for low temperature engines. Problems might be with the non linear graph. 40C might need 1psi. So everything needs to be 15 times the size for the same power as boiling at atmospheric pressure? But you can get night electricity from warmish water, and covered ponds is easy to get lots of this. Need a closed system in the engine half, and a condenser in closed loop in the engine? PV + batteries, not the 1950's? Expect lots from 70 years ago, might still be good, now control is so much easier + precision computerised engineering and parts availability. If you have a 48,000 litre tank of water at 40 C (swimming pool size), you'd be lucky to get 400kWh of electricity. As soon as the temperature goes under 40C boiling anything gets difficult. Need to batch the heat exchange. Heating to 70C+ with PV makes it much better.
I'm assuming we can get more power at lower temperatures with different gases so we will just have to test and find out I definitely want to test different gases
Your throttling is like it's hammer hitting the turbine. Correct the system so that you can gradually bring up the speed, your disk will last longer. The acrylic nozzle that converts the pipe formed air into the shape that is too flow over the turbine is far too short triple that length and throw a temperature sensor on that. (theory that it is ice chucks form there then break off and destroy the turbine blades.) (You may even want to work on placing fins inside the nozzle so that the air hitting the turbine is even more "REFINED" and thus more effective.)
Thank you for the feedback! The Tesla turbine operates differently from traditional turbines, primarily due to its laminar flow characteristics. This means there’s no danger of a hammering effect inside the turbine. The smooth, laminar flow prevents the kind of turbulent impact that could damage the disks. Regarding the throttling method, I'm doing it intentionally for a specific reason. I want to ensure the gas isn't double expanding before it reaches the turbine's inlet. When throttling with a partially closed valve, you lose energy before the gas even enters the nozzle and the turbine, making the system less efficient. That’s why I fully open the valve and pulse the gas through the turbine. This way, all the expansion happens at the nozzle and inside the turbine itself, maximizing efficiency. As for the nozzle design, your suggestion to extend the length and possibly add fins is an interesting idea. I’ll definitely consider experimenting with a longer nozzle and perhaps adding temperature sensors to monitor potential ice formation. However, given the nature of the Tesla turbine, even if ice were to form, it wouldn't have the same destructive impact as in traditional turbines, since there are no blades or vanes to damage. I appreciate your input and will continue to refine the setup. Thanks again for your insights, and feel free to share more thoughts as we continue to optimize the turbine!
Have you thought about using something like a turbo smart E gate to control your flow? If you used something like that then you could put a transducer on the turbine and even use Holly efi programming on a laptop to control it. Just a thought.
@iEnergySupply the electronic turbo waist gate should be more than capable of running your system. You should be able to find several videos on the E gate. Should be the easiest to install and work with. Good luck.
@@bansheeman213 ill take a look, we might use it in the future if what we already built has too many issues, I will be testing it hopefully by this week.
Hello Jeremiah. I was wandering. How much watts can you pull from this small turbine? Is the fluid mixed steam and air? Are you planning On making an endurance test? Like running the turbine for hours or even days.
The power output in these tests was limited by the generator. Theoretically, I could achieve several kilowatts with a more powerful generator, but only further testing will reveal the actual limits.
@@peterfitzpatrick7032 I know Ohms Law; I did see it was between 200 and 500 watts, but I meant to ask about the theoretical limits of this particular turbine.
Amazing Build! This is the first time I have ever seen someone actually build and operate a Tesla boundary layer drag turbine on TH-cam. The experiments are definitely promising. Have you done any experiments with larger disc diameters and say using water/ gravity as feed for one?
Thank you for the kind words! I’m glad you enjoyed the build. I’ve been focusing on optimizing the system with various heat sources and improving efficiency. Check out my previous videos to see my larger 6-inch rotor, which generates significantly more power and is driven by a thermal battery/thermal reservoir. Currently, I'm testing the turbine using a thermal reservoir that can be charged with different heat sources to produce electricity. I have successfully experimented with using water and gravity as well, although I haven’t published that on TH-cam yet. Exploring larger discs could further enhance performance and open up new possibilities.
You could use an idle air control valve from a car or an electronic expansion valve (EEV) from an air conditioner to control the air flow in a more linear way, they both have a stepper inside that you can control easily from software or hardware. It looks like it could possibly take even more load, and then you have tricky job of deciding whether its the generator or turbine that is the limiting factor, the power density looks to be insane, have you done any efficiency calculations including the energy left in the stream after the turbine?
Here is the reason I want the valve either fully open or fully closed. 1. Preventing Partial Throttling When a valve is partially open, it creates a restriction in the gas flow, causing a pressure drop without doing useful work. This leads to what is called throttling losses. In a turbine, you want the gas to expand and accelerate fully as it moves through the turbine’s rotor, converting pressure energy into mechanical work. If the valve is not fully open, you might be wasting energy by having the gas lose pressure across the valve instead of through the turbine blades. This reduces efficiency. 2. Avoiding Double Expansion of Gas If the gas partially expands before reaching the turbine (due to a partially open valve), it loses potential energy that could otherwise be converted into mechanical energy. This is referred to as double expansion, where the gas expands once through the valve and then again through the turbine. Double expansion reduces the effective pressure drop across the turbine, meaning less energy is available for the rotor to extract, which directly lowers the overall efficiency. 3. Maximizing Isentropic Efficiency A fully open valve ensures that the gas expands isentropically (i.e., without unnecessary heat loss or pressure loss due to friction or throttling). This maximizes the turbine’s isentropic efficiency, which is the ratio of the actual work output to the ideal work output. Closing the valve fully, when needed, ensures that no gas flows through the turbine unnecessarily, preventing losses when the turbine isn’t meant to be active. 4. Stable Flow and Control Full open or full closed valve positions provide more predictable and stable gas flow, making it easier to control and optimize the performance of the turbine. Partial valve positions introduce turbulence and irregular flow patterns that are hard to manage efficiently. In summary, fully opening or fully closing the valve helps ensure that the gas flow is either fully utilized for energy conversion or stopped entirely to prevent unnecessary losses, thereby improving the overall efficiency of the turbine system.
@@iEnergySupply these are good points for a final product, that is absolutely what you want but for testing would it not be good to see where the efficiency lies at different turbine pressure vs load?
@@ChrisDay-sx4lv I tend to agree, you may lose efficiency with an EEV or TXV, but you can do a lot more characterization of the turbine for learning and optimizing. In the end iEnergy can probably regulate with a PLC transfer function that reguates by adjusting boiler heat input rather than choking flow with a valve What do you think of PWMing a valve with a very short transitions to eliminate pressure drop losses so it is mostly fully open or fully closed? Or perhaps its best to develop a converging-diverging nozzle that can be deformed to provide efficient throttling functions.
@@InfinionExperiments PWM would not be a good choice, you are just averaging out the losses as the valve is not instantly open or closed at any one time. At his stage of testing it would be wise to concentrate on the efficiency of the turbine and disregard the efficiency of the system IMO.
When you opened the valve to the big tank, I thought it sounded like you had liquid in the tank which comes from the moisture in the air. Obviously, you did and you have to drain that out once in a while. Nevertheless, good video about a Tesla turbine.
Actually I filled the tank up half way with water and heated the water up to add hot vapor to the compressed air. Don't worry though, I regularly test the tank over 150 psi with water so that there is no danger of explosion during testing.
Nice test with humid air if you can make it run for a few hours while it is producing 500 watt that would be something 😀 i wonder what the nozzle diameter is ?
Doesn't the cold steam setup use less applied energy and still get the same output? Also Why does the load slow it down? is it the winding or use of a magnetic field causing a torque or a drag-ah what's the word? I lost my train of thought😢😂. Not static friction..lol. just why. 😅
Great questions! The cold steam setup does use less applied energy due to the efficiency of phase change and heat transfer processes, but the actual output depends on the overall system design and losses involved. As for the load slowing it down, you're probably thinking of 'back EMF' or 'counter torque.' When a load is applied, it creates resistance against the motion, increasing the demand for energy. This can be due to several factors, like magnetic drag, mechanical friction, or electrical resistance in the windings. All these can cause the system to slow down as it tries to maintain balance. No worries, it's a complex topic, and losing your train of thought happens to all of us! 😅
For these smaller turbines, that would be a very useful way to stabilize the RPM. My main turbine project has a much larger rotor made with heavier material, which helps stabilize the RPM. Stay tuned to see this effect in action.
100 psi was the max pressure in these tests. If I increased the water temperature it would run for much longer and if my generator was more powerful I could output much more power.
Have you guys tried or thought of using different fluids? Such as supercritical co2? For off grid that would be good to have backup fluid type options Thanks
We definitely want to explore using them in the future. However, I want to avoid supercritical CO₂, as the high pressures it requires would exponentially increase the system's costs.
Something I have wondered with Tesla Turbines having a hard time converting their speed into torque.... is there a way to use a gear system (like a bike) that can be increased as more momentum is built to spin a series of increasingly large Flywheels or multiple of them in succession to make the motion more useful? Say even as a solar battery system, where they would get faster and more mass during the middle the day and as the solar drops off at say 4pm, then the momentum built by the flywheel could be utilized? In my brain, this idea could also be best used in a hydro dam or on a waterfall or something.
Thanks for your comment and interesting ideas! Regarding torque, the Tesla Turbine operates at extremely high RPMs, which compensates for the lower torque with a high power output. Since power is a function of both torque and RPM, the high speed of the Tesla Turbine allows it to produce substantial power, even with lower torque. In our latest tests, we've seen excellent power output without any torque issues, especially when paired with a generator using air cores. This setup allows us to efficiently transform the high-voltage output into low-voltage, high-amp output using electronics, which suits our needs perfectly. Now, to address your other questions: Using a Gear System and Flywheels: Your idea of using a gear system to gradually engage larger flywheels as momentum builds is quite interesting. In principle, it could work as a form of energy storage, where excess kinetic energy is stored in the flywheels and then released when needed. This would require precise control to engage the gears without losing efficiency, and the system would need to be robust to handle the rapid changes in speed and torque. Solar Battery System: Using this concept in a solar battery system is another intriguing application. The flywheels could store energy generated during peak solar hours and then release it gradually as solar input decreases. However, one challenge would be managing the losses inherent in mechanical systems and ensuring that the stored energy can be efficiently converted back into electrical energy when needed. Hydro or Waterfall Application: In a hydro setting, the consistent flow of water could keep the flywheels spinning, making this a more practical application. The system could potentially act as a buffer, storing excess energy during low demand and releasing it during peak demand, similar to pumped storage but in a more compact and potentially more responsive system. Overall, while these ideas are conceptually sound, implementing them would require careful design to minimize losses and ensure efficiency. For the Tesla Turbine specifically, our focus has been on optimizing the electrical output directly, and so far, it’s working very well with our current setup.
@@iEnergySupply 100% Yes, and it makes sense that you lose efficiency as you add additional mechanisms on to the Tesla Turbine too. Personally, I am just shocked that the Tesla Turbine exists, and that no one has been able to find a real way to make it functional. I am aware that current Hydro powered dams like the Hoover Dam have a +90% efficiency (which is very impressive). I wonder if there is a way to use the Tesla Turbine other than it being a psychological exercise? It feels a bit like Da Vinci's ornithopter... beautifully drawn, interesting concept, but not useful in reality. Who knows. haha
@@iEnergySupply you know I originally thought of gears just to speed up the turbines spinning output... It's just not necessary! That thing spins fast enough, right?
In previous tests, we estimated an isentropic efficiency of approximately 99%, though this was a rough calculation. We are planning further testing with more accurate and precise measurements. While 99% may seem high, particularly when compared to other turbines of similar size, it is important to note that the overall thermal efficiency of such cycles tends to be relatively low. However, our goal is to significantly enhance the thermal efficiency as we continue to refine the system.
@@donavonneighbors Maybe some time we will accept some visitors, I would have to get an ok with my partner. Can I get your email, if you send it delete it shortly after.
Currently, we are working on a system that utilizes a thermal reservoir to power a turbine. My latest tests focus on this approach, which allows for the thermal mass to be charged with almost any heat source to generate electricity.
The problem with very low temperature differentials is you are limited by the carnot efficiency, low temperature differential = low efficiency. That's a big reason we use superheated steam in large scale turbines
Air compressor, but with the new 6" turbine, it's made of aluminum and has a metal rotor so to generate electricity, all you need is to heat the thermal reservoir. You can use firewood, wood chips, diesel, waste oil, gasoline, trash, or even solar thermal energy-basically, any fuel you can think of.
@@iEnergySupply interesting, self made? lightweight, resisting hihg rpm and being much more easy to make by hand than most metals. what expoxy or binder did you use in the carbon fiber(or what material you used at it, not as much interested in the speciffic brand as in the speciffic types since most brands which people on the internet use aren't available here(netherlands)), especially since many epoxies can't handle to high temperatures. similar to plastic.
@@ted_van_loon I used a fairly generic carbon fiber I found online for this build. If I could source a high-temperature-resistant carbon fiber, it would be ideal. I did find a type rated for 500°F (260°C), but after testing, it turned out to be too weak. I made disks from it and spun a 6" diameter rotor up to about 33,000 RPM, but unfortunately, the disk failed and shattered under the stress. Interestingly, FR4 fiberglass has shown to be stronger in some of my tests, despite its limitations with temperature resistance. To avoid issues with heat and mechanical stress, I've switched to titanium for the larger 6" rotor during testing. While titanium is quite expensive, its strength and resistance to high temperatures make it an excellent material for these applications-especially when dealing with high rotational speeds and thermal challenges. It’s proven to be a real game-changer for this project.
@@iEnergySupply plasma steam systems of which I don’t know much but I know steam allows for charge separation which is a key component of the magic of plasma. There are commercially available units found in Google. Other way include spark gap this might sound crazy but could you use the housing as a cathode and turbine discs as an anode ? Another way would be to generate EVO’s a form for plasma similar to ball lightning via shear and cavitation like Kladov or Cavitation by water hammer like Bin Huang. All the info for those systems is available on the Martin Fleischmann Memorial Project on TH-cam
Weird my first reply didn’t stick. But I mentioned the work of Kladov, Bin Huang, Ken Shoulders, Matsumoto. They all in different ways created charge separation which led to the formation of EVO’s aka ball lightning. I also know that steam at certain temperatures is a state of water which generates charge separation. There are commercially available plasma steam units for many things. My favourite idea is make the housing the cathode and the discs the anode and pulsing HV AC with constant DC ! Bin Huang system uses steam recycling the water is key as the EVO’s build up and more of the magic happens. All the above mentioned is available on the Martin Fleischmann Memorial Project has a Page on TH-cam. Be sure to look through the Live Videos. Plasma is used by the military to go ultra sonic when you posted about breaking the sound barrier, I immediately thought wouldn’t that be something. Tesla was a big fan of plasma and ball lightning. Only makes sense that you make the steam plasma for his turbine
@@iEnergySupply I should mention it that a lot of these devices create strange radiation find videos regarding this on the Martin Fleischman Memorial projects page if you see any of these that you watch thosevideos on safety. Also, if you did ever pursue a system use cavitation ,implosions from cavitation are destructive precautions must be taken
Dude, you don't need to show rip'ems. You can just show the hz of the power being generated. That's basically the same as showing RPM. Flip that fake Fluke from flow to Hz.
I tried, but the frequency became unstable at around 32,000 RPM. To measure the RPM, I analyzed the sound using the Spectroid app, which I’ve found to be very accurate when compared to an actual RPM meter. In this test, using an RPM meter wasn’t possible because the shaft was not exposed.
One thing I'm wondering is, since you have to use electricity to use the compressor, even if you run a tesla turbine, you still have to use external electricity, so in conclusion, you're generating electricity, but isn't it offsetting?
To generate electricity, all you need is to heat the thermal reservoir. You can use firewood, wood chips, diesel, waste oil, gasoline, trash, or even solar thermal energy-basically, any fuel you can think of. The versatility of that is truly amazing!
The compressor is only used at start up, once it gets going, you can turn off the compressor and it keeps running until all the energy from the hot tank is used up
@@PhillyEaglesFanaticYes, after you pull a vacuum on the main system, the vacuum pump doesn’t need to be turned on again unless there are leaks in the system.
Ok INsANE idea what if you inject a fuel air mixture into the turbine, have the turbine spit it out of its exhaust, then ignite the exhaust and feed it into an axial turbine. TESLA turbine Turbojet
lol now you can boiling the kettle with enough air providing a major bearing failure doesnt occur which it will without oil feed and/cooling. Damn it, back to the drawing board once again😂😂🤣
These bearings have withstood several rotor crashes caused by misalignment, which I've since corrected. Amazingly, I've been testing with the same bearings for over 4 years, and they’re designed to run without oil. With the alignment issues resolved, no more crashing rotors! My new 6" turbine is now bulletproof. Cheers!

I hope you continue to find value in both of our approaches! I’d rather not get into specifics, but I’m always open to connecting with other creators who share the same passion.
@@iEnergySupply water can cause drag and rust etc. Especially in bearings. We use water traps on all of our air compressors in my work shop. Just thought id mention it 😎👍
In principle you expand almost the whole pressure within the nozzle in order to make as much kinetic energy of the gas flow as possible. You only use a very small fraction of total pressure drop to drive the gas through the turbine gaps. You only need the remaining pressure drop to generate enough torque to compensate the torque of the generator and some friction losses. I don't understand why you spiral the flow from the outer rim to the inner rim of the gaps. It doesnt make sense because it generates only much more friction than you really need. I would keep the flow at the outer rim of the gaps in order to release it after a half of the perimeter. So you have nearly constant streaming conditions and it is easy to calculate. When you find that the outer rim of your turbine goes supersonic than you know, that you work not very efficient. The maximum speed of the gas flow, you can reach ist sound speed. If you want supesonic flow you have to use a Venturi nozzle (with diffusor). So the outer rim of your turbine is faster than the gas flow at the end of the nozzle. It means the outer rim of the nozzle acts as a break, which ist driven by the inner gap section. This is also the reason why I don't like Tesla's turbine design, because it is simply not very efficient. You don't realize this inefficiency, because you have a lot of power in your gas flow. Using only the outer rim of the turbine gaps is also useful to get a compact turbo generator design. You can put permanent magnet disks in the inner rotor part which operate on stator air coils in the turbo generator housing plates (4 permanent magnets and 3 coil pairs on both housing plates). In this way you will get an axial flux generator without iron losses.
Thank you for your insightful comment! You've raised some important points about the efficiency of Tesla's turbine design and the potential for supersonic flow at the outer rim. One of the core principles behind Tesla's turbine is rooted in his understanding of fluid dynamics, particularly the importance of allowing fluids to move in natural spiral paths with minimal resistance. According to Tesla, this design helps avoid the sudden changes in velocity and direction found in more conventional turbines that rely on blades or vanes. The spiral movement of the fluid, influenced by the adhesion and viscosity properties, allows for a more gradual transfer of energy as the fluid moves toward the center of the disks. This gradual transition minimizes the losses associated with shocks and disturbances that you’d see in traditional turbines. While your suggestion of maintaining the flow at the outer rim for constant streaming conditions is logical, Tesla’s design deliberately uses the spiral inward motion to continuously reduce the velocity of the fluid and extract as much energy as possible over the entire flow path. By the time the fluid reaches the center, it has already imparted a substantial portion of its energy to the turbine. Tesla himself noted that “the performance of such machines augments at an exceedingly high rate with the increase of their size and speed of revolution.” This suggests that while the design may seem less efficient in theory, in practice, the fluid's interaction with the entire disk surface optimizes the energy extraction process. Regarding your observation about supersonic flow, Tesla designed the turbine with the idea that, under normal conditions, the fluid’s velocity should match the peripheral speed of the disks. When the turbine is properly scaled and tuned, the speed of the fluid and the turbine's edge should remain subsonic. Tesla acknowledged that if there’s too much velocity mismatch, inefficiencies can arise, but he accounted for this by recommending increased disk area or reduced spacing, depending on the fluid properties.
@@iEnergySupply hm, when you design a turbine which spirals the flow from the outer rim to the inner rim of a spacing between disks you accelerate the flow from the outer rim to the inner rim because you decrease the static pressure in order to transfer it into dynamic pressure. But along the path the transversal velocity of the disk is decreased. This means the difference between the gas velocity and the transversal disk velocity gets higher and higher. This means the friction becomes higher and higher. At the end of the process you will get a very stange equilibrium where you generate a lot of friction and your gas tends to return to the outer rim of the disk space but the static pressure in the outer gas spirals acts in a way to suppress this tendency. I cannot imagine that this equilibrium state is somehow characterized by a good transfer rate of kinetic energy from the gas to the disk. In my experiments I have found that the best efficiency comes with relatively constant but slidely increasing gas velocity, where the velocity difference between gas and disk is more or less constant and small enough that you don't waste too much energy into gas friction. In a bladeless turbine you need some dissipative friction in order to transfer the torque. But you just need the torque to drive your high speed generator, which is relatively small. You generate your mechanical and electric power in turbine engines mainly with your angular velocity and not with your torque. P = 2*pi*f*T P: mechanical power [W] f: frequency of rotation [1/s] T: torque [Nm] So, the best you can do is to keep the gas at the outer rim of your disk space and to keep the gas velocity constant and slidely higher than the disk's transversal velocity. Only in this way you loose the smalles amount of power due to friction. So the most power ist transferred to the disk. With an inward spiral you can probably get more torque but you lose a lot of power due to friction. This is probably also the reason why your rotor immediately accelerates very hard. But this is not the way to make an efficient turbine. A turbine lives from the gas speed and not from the gas friction. A turbine accelerates smoothly to its nominal speed. Only dental turbines are designed to generate a lot of torque at lower speed. But they are not optimized for higher efficiencies. These turbines are not active but reactive turbines Their blades stand like a wall in the gas flow like in a mixture of a pelton turbine and a rotary vane pump. They are mainly (stagnation) pressure driven engines and act more like piston engines.
@@gkdresden The phenomenon you described is something I generally agree with in terms of fluid dynamics and turbine efficiency. However, in the case of the video you're referring to, the reason the turbine didn’t start immediately was actually something I hadn't seen before. Upon inspection, I found that the rotor wasn’t properly aligned and was making contact with the side wall. This misalignment caused the rotor to scrape the side wall, and I had to overcome the friction of this contact before the turbine could start. This aligns with the broader point you made about friction, but in this case, it was an unintended mechanical issue rather than a design characteristic of the turbine. Additionally, as you mentioned regarding the transfer of energy, it's important to note that by ensuring proper construction and observing working conditions, the centrifugal pressure opposing the fluid's passage can be made nearly equal to the supply pressure when the turbine is running idle. If the inlet section is sufficiently large, even small variations in rotational speed can result in significant differences in flow. This effect is further amplified by the changes in the spiral path length, creating a self-regulating machine. This concept bears a resemblance to a direct-current electric motor, where significant differences in impressed pressure are counteracted by the rotation, preventing excessive fluid flow. It's also worth noting that due to the laminar flow within the turbine, this self-regulating behavior becomes possible. The fluid passage through the turbine can remain highly efficient, as the system only uses as much flow as required for a particular load. This ensures that the turbine's efficiency remains high while minimizing unnecessary flow, further optimizing performance under varying conditions. In the case of my turbine, this issue was compounded by the friction caused by the rotor's misalignment, but your point on efficiency is well taken.
actually while partly true and seemingly true, it is actually not fully true, that is because the tesla turbine's working is actually far more complex and advanced than it seems, but 99.99% of science and even the people explaining them and such do not properly understand the engine. several years ago when I made my first 3d printed tesla turbine I noticed some odd behaviour and using that managed to figure out it's actual working. this is also backed by how nikola tesla was great in geometry optimizations, yet somehow speciffically said the room needed to be round, and also didn't say you needed a special nozzle. essentially I rediscovered the way the tesla turbine was actually meant to work, and did some reseach and a more complex advanced version of simulations on it(actually the same type of simulation nikola tesla used to test his mashines which up to today still is much more accurate and faster than computer simulation programs). but the interesting things I found where : 1: you don't need a nozzle since the tesla turbine generates a relative aerospike, this is similar to that new technology in rocket engines, but it already was there around 100 year ago in the tesla turbine, the aerospike in the tesla turbine however automatically dynamically adjusts itself and also acts as a nozzle. 2: the tesla turbine relative adaptive aerospike nozzle not only extends at the inlet but through the entire device, forming a adaping dynaming converging divergent nozzle, which actually is a type of nozzle used in rockets to make them go faster than sound, but in rockets they are fixed so only efficient at a very speciffic speed, while in the tesla turbine it is much more powerfull. essentially in most cases adding a nozzle or such will decrease efficiency. and a tesla turbine can go faster than sound on it's own while remaining efficient. that said when going much faster than sound you start to run in other ineficiencies no mather what turbine you use.
@@ted_van_loon It’s great to hear from someone who’s done such thorough research! I’ve long suspected that the divergent section of the nozzle isn’t necessary within the nozzle itself, and your findings about the adaptive aerospike behavior of the Tesla turbine validate that. The way the turbine’s spiral flow through the disk gaps naturally acts as the divergent section makes perfect sense, essentially allowing supersonic flow without the need for a traditional nozzle. The idea of the turbine dynamically adjusting its flow path and essentially forming a converging-diverging nozzle throughout the entire device is brilliant. It truly reflects Tesla’s genius in optimizing geometry-something that’s still not fully understood by most modern explanations. The fact that the turbine can generate and adjust its own aerospike shows how advanced the internal fluid dynamics really are. I don’t think most people, or even modern simulations, fully grasp how intricate this system is. I also agree that adding a nozzle can reduce efficiency in many cases. The Tesla turbine is inherently more powerful when left to its own dynamic flow adjustments. It’s remarkable that this technology can achieve supersonic speeds while maintaining efficiency, unlike fixed-nozzle systems. But as you pointed out, even when the turbine exceeds certain supersonic thresholds, some inefficiencies start to appear-this seems to be an unavoidable limitation for any turbine at extremely high velocities. It’s exciting to think that Tesla had already figured this out over a century ago, and how much more efficient his approach was compared to many modern systems. I’d love to see more people dive deeper into these core principles-understanding them could truly revolutionize how we apply this technology today! I do have a question for you, though: when I run my turbine in a vacuum and get the rotor spinning close to the speed of sound, if I turn off the gas inlet, the rotor maintains its speed for a long time due to the low atmospheric pressure. I’m wondering, based on what Tesla described about using pulses of gas as the most efficient way to run the turbine, could this approach reduce the negative effects of running the turbine at such high velocities in a vacuum? Perhaps the low pressure environment could make the pulsed gas more effective by minimizing turbulence or drag? I'd be curious to hear your thoughts on this.
Vidéo intéressante, mais le principe de fonctionnement n est pas expliqué. Construire cette machine est intéressant mais y a t il des applications industrielles ( commerciales) pour créer de l électricité à prix faible? Sinon quel est l intérêt d avoir construit cette machine? Est ce une machine rentable ? Une 2ème vidéo plus détaillée et expliquée serait la bienvenue.
Merci pour votre commentaire ! J'apprécie votre intérêt. Le principe de fonctionnement de la turbine Tesla repose sur la friction de la couche limite, où le fluide se déplace en spirale entre des disques étroitement espacés, transférant ainsi de l'énergie aux disques sans avoir besoin de pales traditionnelles. En ce qui concerne les applications industrielles ou commerciales, bien que les turbines Tesla ne soient pas largement utilisées aujourd'hui dans la production d'énergie à grande échelle, elles ont un potentiel dans des domaines spécifiques, comme la récupération de chaleur perdue, la production d'électricité à petite échelle, et la production d'énergie à faible coût à partir de sources renouvelables comme la géothermie ou le solaire thermique. La simplicité de leur conception pourrait entraîner des coûts de maintenance plus bas par rapport aux turbines traditionnelles, même s'il reste encore des défis techniques à relever pour une utilisation à grande échelle. Je suis d'accord qu'une explication plus détaillée serait utile. Je prévois de réaliser une vidéo de suivi où j'expliquerai en profondeur les principes et les applications potentielles dans le monde réel. Restez à l'écoute !
Try to get in Touch with Peter Lindeman and Aaron Murakami, they will tell you that tesla intended his turbine to work in sister conjunction with another as a 99.9% heat->motion konverter using "cold" steam. nonetheless nice work keep it up
I work in Aaron's shop, haha. Achieving 99.9% conversion of heat would be the ultimate dream. I hope it happens one day, but it's a very difficult feat of engineering.
A terubine is a highly sophisticated machine that generates power using nothing but typos and awkward moments. Sadly, I haven’t perfected it yet... still working on spelling 😂
@@SINHRO-FAZA Это забавно - мой самый тихий турбина был настолько бесшумным, что люди думали, что он фейковый! Они спрашивали: 'Почему его не слышно?', потому что они привыкли к очень громким турбинам.
Speed is actually more crucial than most people realize when it comes to the Tesla turbine. If done properly, it can become a self-regulating machine-kind of like a DC motor. Even if the pressure changes a lot, the rotation controls the fluid flow. What's cool is that the centrifugal force increases with the square of the rotational speed (or even faster in some cases), so higher speeds really make a huge difference. With modern high-grade steel allowing for crazy high peripheral velocities, it's possible to reach that self-regulating state in just a single stage, especially with a larger diameter runner. So yeah, speed is a major factor here, more than it might seem at first!
Or we could just increase the temperature, which isn’t too bad for a laminar flow turbine. However, I’m curious to see how a dryer would perform in this setup.
That seems fairly inefficient. The 500W extracted from the turbine compared with the couple kW to go into supplying the air to make that 500W. Running the generator at high frequency is potentially problematic depending on the rectifier. The 1500Hz isn't really fast but the high current rectifier might be quite slow. The relatively low voltage of 50V is also quite lossy if you're using a silicon diode rectifier. It'll have 1.4-2.0V across it depending on it's specs and the current. This means that you're losing about something like 4% of the energy just in rectifier losses. You can get a frequency measurement in real time quite easily if you use 1 of the 2 meters on the Hz range.
I suspect you actually know the energy efficiency is about energi in vs energy out, not power in vs power out. Still, one small Tesla turbine can't be very efficient. Your point about losses in rectifying the voltage is valid, if it the voltage is rectified, which isn't necessary to run incandescent lights. They can redesign the generator to increase the voltage. They're experimenting, not showing a finished product for sale. Also, ~4% additional loss in rectifying isn't much in that context. Consider the videos as entertainment. BTW nice to see that you use the proper unit symbols, I think the convention is leaving a space between the number and the symbol in common text, but hey, just using the right symbols is rare in youtube comments.
Thanks for the detailed input! You’re right; there are efficiency challenges when matching the input power to the output. The goal of this setup was to demonstrate the concept and the potential of using various heat sources to drive the turbine. I’m currently focused on optimizing the entire system, including the generator and rectification stages, to reduce losses. For the main project, I’m working on a larger turbine paired with a coreless generator that outputs 400V. With this higher voltage, the rectifier losses should be much lower, making the system more efficient. I’m also considering using more advanced rectification methods, like Schottky diodes or MOSFETs, to further reduce voltage drops and improve overall performance.
You haven’t seen my latest progress on the large turbine. You can also convert torque from a generator to a motor to get as much torque as you need. However, comparing the two isn’t really relevant because the turbine serves a completely different purpose than a piston engine for what I am doing.
With the right construction and conditions, the centrifugal pressure can almost match the supply pressure when the machine is idling. If the inlet is large, small changes in speed can cause big differences in fluid flow, helped by changes in the spiral path length. This creates a self-regulating machine, similar to a DC motor, where fluid flow is restricted by rotation, even with big pressure differences. Since centrifugal force increases with the square of speed, and modern steel allows for high velocities, this can be achieved in a single-stage machine, especially with a large runner.
@@timh.2137 fffs, it isnt even worth explaining... but i will anyway, though i get the impression you wont understand, or want to understand. if the air is supersonic, and the blade moving within that air is also supersonic, it doesnt produce a "boom" because the relative speed between the two is NOT supersonic. anyway, a "boom" is a single wavefront, a single rapid rise of pressure, moving past you. not a continuous sustained note. when a propellor tip exceeds SoS, theres also no "sonic boom", but it does make an awful "tearing" sound... very distinctive. fun fact, air exiting a nozzle at anything over 16 or so psi is already travelling at sonic speeds...
The terubine is a turbine with a 1000x more bines than a gigubine, and a 1,000,000x more bines than a megubine. That's why he lowered the pressure. The tur/bine ratio is way off and you have to lower the speed to get the right ratio.
Why are you here? Seems a lot of oddball haters with no interest in this video sure are commenting. Its highly illogical for such people to have converged on this video and then choose to comment. Not a word showing true interest
Any gremlins or mystery issues been occurring these part couple years? Just curious for various reasons. 🫀 i truly enjoy hearing the genuine joy and excitement in your voice 5:43 8:47 let me remind you, “these tesla turbines don’t work. They can’t truly generate anything useful “ Official quote of the 🥴in’errNet🤡 ( in error forever stuck beneath a net of inept auto accept of all things. Gazing through an askew film covered lens of Rote memorized law and theory which never bends nor breaks. Hands on a single physical thing, such acts never makes. Endlessly Unoriginal.

Nothing weird has happened so far-no gremlins. I did have a turbine stolen once, though, from my car. I turned my head for a moment while talking with my dad, and it was gone. Someone knew exactly what they wanted, and I have no idea how they even knew it was in my car.

I always love the laminar flow of the Tesla turbine . 10 years of age I was using the hose to clean out a Paint roller and found that I could get it spinning at great speed just by squeezing the end of the hose to create more pressure and I've been fascinated by the concept and of course people have been building wonderful little Tesla turbines and as much as it's not the answer to all things it certainly has its place that is just not being really utilised micro energy. Storage as every time you turn your tap on on your house or have a shower that could pressurise air first spin up a Tesla turbine for a period of time and stole the energy into batteries that could use for nighttime lighting in a house so Justin the water supply that is pressurised we lose all the energy by not taking advantage of it when we open the faucet in the Home and in fact in the 1940s or somewhere near there they did actually have these little dynamos. I think in England that used to create, a small amount of electricity for whatever use they had then
Amazing, simply amazing. I look forward to further progress in this area.
Thanks 🙂Progress is inevitable!
Yes boi!!!! So stoked you put an update out for us!!!
More to come!
Great Jeremiah! Thank you for sharing your progress. One very intriguing application for the tech, aside from the whole our-of-the-grid home thing, is as an addition to a ICE water cooling system for hybrids, to recharge the car batteries not only with the mechanical power of the rotating shaft, while the ICE is running, but also with the most of the heat which usually is wasted away (about 60-70% of the total energy) through the radiators.
Thanks! I would love to start the R&D on that as well, just waiting to get through production on the main project to finish other areas.
Excited to witness your results.❤
Thanks!
Outstanding performance Jeremiah!
Thanks!
Pretty cool Jeremiah, you've come a long way bro. Keep going!
Thanks!
You may even open up another branch of physics at these speeds. Next, you can approach 10 percent the speed of light. Use this as a rocket to explore the stars. Keep up the amazing work.
I was hoping to open a black hole.
@@iEnergySupply
The black hole is already open you just have to enter. 💫✨
pfft 95,000 rpm is nothing in mechanical physics, youve got much to learn.
@@Th4thWisemanbut for some water turbine it is
You have water jetting. (Take the issue of compressed air when there is a pressure drop results in a lowering of the temperature (Measure that water temp over time) IF even condensation hits expanding air you stand a chance of ice forming somewhere in the system that then breaks off and collides with the turbine. It doesn't take much to destroy the balance in the turbine.
Thank you for the comment! You raise a very valid point. The issue of temperature drop due to the expansion of compressed air is indeed a critical factor to consider in such systems. As the air expands, the temperature can drop significantly, potentially leading to condensation and even ice formation, depending on the humidity level and temperature conditions.
I've only encountered this issue under specific circumstances, such as when a strong vacuum was created by a pump stage attached to the same shaft, running both compressed air and water vapor inside the turbine. This could potentially be mitigated by using higher temperatures for the air. However, this system isn't designed for compressed air. If you check out my previous videos, you'll see that I use the Rankine cycle, and I haven't had any issues like those you're describing.
The scenario could change if I were to use a powerful enough pump to decrease back pressure and increase the expansion ratio. But even then, since the turbine operates under vacuum conditions, the likelihood of ice formation remains low. Additionally, even if ice were to build up on the disks, it would be unlikely to cause damage. Unlike conventional turbines, which have buckets, paddles, or vanes that could be impacted at high speed, the Tesla turbine’s design minimizes this risk.
Thanks again for your input, and please keep sharing your insights. It's always great to discuss these technical nuances with the community!
@@iEnergySupply Jerrmiah youre truly inspiring. A great example of a real true heart. 🫀
Absolute GOATTT! Greatest of All Time Tesla Turbine!
Wish we had a better generator for it. We just need to upgrade those ferrite cores to iron cores.
225w under load x 24 hrs is barely 5.5kwh @ 30v x 7.5a per hr if it could run for an hr lol, i love the idea of this tech i just realllly hope it scales as well as i think it should. not hating but if you want anyone to take you serious slap a gear system on this and attach a damn 5kw axial flux alternator and get hella watts per hour or die trying lol, this with a 22kwh per day output could power a house with solar heating in alot of places. dope build keep it up i hope something like this replaces reactors one day.
Check out my previous video: that was a polycarbonate turbine, so I couldn't let it get too hot. I've managed to generate over 2 kW with it. My new turbine, however, features an aluminum housing and titanium disks, and it's capable of much more. It can easily exceed 5 kW and has the potential to reach 40 horsepower if operated at high enough pressure and temperature-assuming the shaft can handle the torque without twisting off.
You should get an inlet needle valve for higher levels of control. That way you could ramp it up and see how much flow you need to start it spinning at certain loads, if that's something you care about.
I want the flow to be fully open that way I am not double expanding the gas. This will be more useful with my later experiments going on right now.
@@iEnergySupply That's fair
I've done similar experiments, I found that with the same airflow but at different attack angles for different RPMs, there are big gains in power out.
Did you do that with a Tesla turbine? If so, consider using a larger inlet and increasing gas flow. That way, there won’t be too much friction slowing down the vortex at the periphery of the casing, where the rotor tips are closest to the sidewall. With small nozzles, you will have much thinner boundary layers, so pointing the nozzle away from the sidewall, as you described, helps.
You’re an inspiration Jermiah. I watched one of your previous videos with a heat source and a condenser at vacuum. Couple years later watching another video on desalinization I realized that is the cheapest form. Basically using horizontal black pipe on the desert sand , A reverse P-trap leading into a T, One end of the T goes into a vacuum pump which could be a tesla turbine maybe and the other end goes back under the ocean to condense the freshwater as it boils around 30° C. Another pump to pump the fresh water in the holding tank on shore. Once the dissolved gases boil off first then close the vacuum valve and we should have a self-sustaining vacuum with boil and condensation.
Another way to do it is by using the temperature difference between the ocean's surface and below. Either method would work. You would likely also want a different working fluid or gas that boils at lower temperatures due to the small temperature delta.
@@iEnergySupply yeah that’s what you’re doing to make power which is awesome but this is for freshwater. Makai Ocean engineering Did a test Plant at the natural energy laboratory of Hawaii doing what you suggest. They have a net gain and they’re making power.
The Denser your working fluid is, the greater the energy that will be transferred to the disks. Increasing Disk mass and diameter
will yield greater torque. Greater torque means lower speeds will yield greater power transfer from the working fluid. Think in
terms of spiral tapering blades inside of a cone structure. Greater surface area yields greater torque and energy transfer.
Interesting project!!
Thanks for the feedback! We've actually built and tested the 6" rotor with great success. Contrary to your point, we've found that higher speeds actually mean more power with less torque, although the torque is still quite substantial. The turbine achieves its greatest power output when the rotor is moving at half the speed of the working fluid. In a vacuum, the steam velocity is extremely high, which makes it feasible to extract energy at very high peripheral velocities.
We've also designed and built an efficient high-speed dynamo that works exceptionally well with this setup, allowing us to achieve extraordinary power output. The combination of high speed, vacuum conditions, and our dynamo design really pushes the efficiency to the next level.
Thanks again for the interest-exciting times ahead with this project! Let me know what you think.
Very awesome. Keep up the good work
Awesome. This is the answer to a decentralized energy grid
That's my aim!
I appreciate how relatively safe this is
Never had a serious accident, but if I wasn't prepared for the worse when I was learning about all the dangers, I could have been seriously hurt.

You should have a blast shield around that turbine. It will kill you if it explodes.
That’s why there’s a blast shield around it. A magnet exploded during a previous test at 99,800 RPM, but I was protected. In the future, we can reinforce it with carbon fiber or Kevlar wrapped in epoxy to make it stronger.
@@iEnergySupply actually i agree with him, the Plexiglas is not thick enough i would want double to be sure, at least use another shield in front of the one you have, the perimeter of that disc is probably going close to 500m/s thats close to bullet speeds.
@@ChrisDay-sx4lv Thanks for sharing your thoughts on this! To clarify, I’m using polycarbonate (Lexan) rather than Plexiglas for the blast shield. Lexan is significantly more resilient and is commonly used in ballistic protection due to its excellent impact resistance and energy absorption.
For context, I once shot a 0.5-inch Lexan sheet with a .22 rifle, and it penetrated only about 0.25 inches. Given the high speed and mass of the lead bullet, this performance is impressive. The turbine casing is made from 3/4-inch Lexan, totaling 1.25 inches in thickness, which is more than sufficient to contain any potential debris from an explosive failure.
For those considering replicating this blast shield, the method of joining the Lexan panels is crucial. Strong, secure joins are essential to ensure that the structure remains intact, as poorly bonded seams could be vulnerable to shrapnel.
Additionally, the turbine’s discs are made from lightweight carbon fiber. While the periphery speeds are extreme, carbon fiber is much lighter than hardened steel or stainless steel, meaning it carries significantly less kinetic energy upon failure. This reduces the overall risk, but safety always comes first-so ensuring proper construction is key to a safe setup.
@@iEnergySupply you covered all the points I was going to make, Lexan really is tough stuff, hopefully its glued as well as screwed, the rear side of the turbine is exposed and you are working close to it, you should at least have something so a ricochet doesn't pose a threat. keep up the good work workmanship looks exceptional, Hope you release some efficiency data soon.
More testing on the way, including Efficiency.
I suggest using Current Clamp for the Amps so you're not limited to 10A. You can get normal DC current clamp multimeter or get something more precise like PeakTech 4250 (20 or 60A) which has great value for the money and 4mm banana plugs for the multimeter. It's the same hardware as Pico TA018 but without BNC and shielding - which you can add yourself for cheap. Not to mention this hardware is mainly used with the oscilloscope so you have current frequency response up to 20 kHz.
Looks like the project is getting further and better, keep up the good work!
I have a clamp-on ammeter, which I initially planned to use, but it wasn’t reading correctly. I later realized it was set to AC mode. Next time, I'll make sure to use it properly in the correct mode.

How long could you run it to say power a home or charge a large battery bank for later energy use?
If you saw the larger turbine before I tested the smaller one, that larger turbine is the one that can power your house. You just need to heat the thermal mass/battery to a suitable temperature.

The upgrade on turbines has so much potential.In real practical electric generation clean.With natural gas
Thank you for your comment! I completely agree-the potential for Tesla turbines in clean and efficient electric generation is huge, especially when combined with natural gas. Unlike traditional turbines, Tesla turbines can handle a variety of working fluids, and their unique design allows for efficient energy conversion with minimal mechanical wear.
Integrating Tesla turbines with natural gas could provide a cleaner alternative to conventional power generation, as they can operate efficiently even at lower pressures and temperatures. This makes them ideal for distributed energy systems and microgrids, where they can be used for local power generation with lower emissions.
We're continually exploring ways to optimize and scale this technology for practical applications in sustainable energy. Stay tuned for more updates as we push the boundaries of what's possible with this innovative design!
I love the cold steam/vacuum boil solution. Why is that not more commonly used? Even in your experiments? Too hard to maintain a a high vacuum?

@@kingrara5758 Thanks!
You're right, using low pressure water is safer than organic solvents for low temperature engines. Problems might be with the non linear graph. 40C might need 1psi. So everything needs to be 15 times the size for the same power as boiling at atmospheric pressure? But you can get night electricity from warmish water, and covered ponds is easy to get lots of this. Need a closed system in the engine half, and a condenser in closed loop in the engine? PV + batteries, not the 1950's? Expect lots from 70 years ago, might still be good, now control is so much easier + precision computerised engineering and parts availability. If you have a 48,000 litre tank of water at 40 C (swimming pool size), you'd be lucky to get 400kWh of electricity. As soon as the temperature goes under 40C boiling anything gets difficult. Need to batch the heat exchange. Heating to 70C+ with PV makes it much better.
I'm assuming we can get more power at lower temperatures with different gases so we will just have to test and find out I definitely want to test different gases
Keep going!
That's the plan!
Wow thats a bigger setup than the last time I was at the Lab. Looking good, any thoughts on recycling the steam back into the system ?
Yeah it is a closed loop, the water is pumped back in.
well done
Thanks!
Really cool!
thanks!
Your throttling is like it's hammer hitting the turbine. Correct the system so that you can gradually bring up the speed, your disk will last longer. The acrylic nozzle that converts the pipe formed air into the shape that is too flow over the turbine is far too short triple that length and throw a temperature sensor on that. (theory that it is ice chucks form there then break off and destroy the turbine blades.) (You may even want to work on placing fins inside the nozzle so that the air hitting the turbine is even more "REFINED" and thus more effective.)
Thank you for the feedback! The Tesla turbine operates differently from traditional turbines, primarily due to its laminar flow characteristics. This means there’s no danger of a hammering effect inside the turbine. The smooth, laminar flow prevents the kind of turbulent impact that could damage the disks.
Regarding the throttling method, I'm doing it intentionally for a specific reason. I want to ensure the gas isn't double expanding before it reaches the turbine's inlet. When throttling with a partially closed valve, you lose energy before the gas even enters the nozzle and the turbine, making the system less efficient. That’s why I fully open the valve and pulse the gas through the turbine. This way, all the expansion happens at the nozzle and inside the turbine itself, maximizing efficiency.
As for the nozzle design, your suggestion to extend the length and possibly add fins is an interesting idea. I’ll definitely consider experimenting with a longer nozzle and perhaps adding temperature sensors to monitor potential ice formation. However, given the nature of the Tesla turbine, even if ice were to form, it wouldn't have the same destructive impact as in traditional turbines, since there are no blades or vanes to damage.
I appreciate your input and will continue to refine the setup. Thanks again for your insights, and feel free to share more thoughts as we continue to optimize the turbine!
Have you thought about using something like a turbo smart E gate to control your flow? If you used something like that then you could put a transducer on the turbine and even use Holly efi programming on a laptop to control it. Just a thought.
We are going to use something similar to that.
@iEnergySupply the electronic turbo waist gate should be more than capable of running your system. You should be able to find several videos on the E gate. Should be the easiest to install and work with. Good luck.
@@bansheeman213 ill take a look, we might use it in the future if what we already built has too many issues, I will be testing it hopefully by this week.
Hello Jeremiah. I was wandering. How much watts can you pull from this small turbine? Is the fluid mixed steam and air? Are you planning On making an endurance test? Like running the turbine for hours or even days.
Ohms Law will tell you... you have the voltage & the current readings... 😏
The power output in these tests was limited by the generator. Theoretically, I could achieve several kilowatts with a more powerful generator, but only further testing will reveal the actual limits.
@@peterfitzpatrick7032 I know Ohms Law; I did see it was between 200 and 500 watts, but I meant to ask about the theoretical limits of this particular turbine.
Amazing Build! This is the first time I have ever seen someone actually build and operate a Tesla boundary layer drag turbine on TH-cam. The experiments are definitely promising. Have you done any experiments with larger disc diameters and say using water/ gravity as feed for one?
Thank you for the kind words! I’m glad you enjoyed the build. I’ve been focusing on optimizing the system with various heat sources and improving efficiency. Check out my previous videos to see my larger 6-inch rotor, which generates significantly more power and is driven by a thermal battery/thermal reservoir. Currently, I'm testing the turbine using a thermal reservoir that can be charged with different heat sources to produce electricity. I have successfully experimented with using water and gravity as well, although I haven’t published that on TH-cam yet. Exploring larger discs could further enhance performance and open up new possibilities.
You could use an idle air control valve from a car or an electronic expansion valve (EEV) from an air conditioner to control the air flow in a more linear way, they both have a stepper inside that you can control easily from software or hardware. It looks like it could possibly take even more load, and then you have tricky job of deciding whether its the generator or turbine that is the limiting factor, the power density looks to be insane, have you done any efficiency calculations including the energy left in the stream after the turbine?
Here is the reason I want the valve either fully open or fully closed. 1. Preventing Partial Throttling
When a valve is partially open, it creates a restriction in the gas flow, causing a pressure drop without doing useful work. This leads to what is called throttling losses. In a turbine, you want the gas to expand and accelerate fully as it moves through the turbine’s rotor, converting pressure energy into mechanical work.
If the valve is not fully open, you might be wasting energy by having the gas lose pressure across the valve instead of through the turbine blades. This reduces efficiency.
2. Avoiding Double Expansion of Gas
If the gas partially expands before reaching the turbine (due to a partially open valve), it loses potential energy that could otherwise be converted into mechanical energy. This is referred to as double expansion, where the gas expands once through the valve and then again through the turbine.
Double expansion reduces the effective pressure drop across the turbine, meaning less energy is available for the rotor to extract, which directly lowers the overall efficiency.
3. Maximizing Isentropic Efficiency
A fully open valve ensures that the gas expands isentropically (i.e., without unnecessary heat loss or pressure loss due to friction or throttling). This maximizes the turbine’s isentropic efficiency, which is the ratio of the actual work output to the ideal work output.
Closing the valve fully, when needed, ensures that no gas flows through the turbine unnecessarily, preventing losses when the turbine isn’t meant to be active.
4. Stable Flow and Control
Full open or full closed valve positions provide more predictable and stable gas flow, making it easier to control and optimize the performance of the turbine. Partial valve positions introduce turbulence and irregular flow patterns that are hard to manage efficiently.
In summary, fully opening or fully closing the valve helps ensure that the gas flow is either fully utilized for energy conversion or stopped entirely to prevent unnecessary losses, thereby improving the overall efficiency of the turbine system.
@@iEnergySupply these are good points for a final product, that is absolutely what you want but for testing would it not be good to see where the efficiency lies at different turbine pressure vs load?
@@ChrisDay-sx4lv I tend to agree, you may lose efficiency with an EEV or TXV, but you can do a lot more characterization of the turbine for learning and optimizing.
In the end iEnergy can probably regulate with a PLC transfer function that reguates by adjusting boiler heat input rather than choking flow with a valve
What do you think of PWMing a valve with a very short transitions to eliminate pressure drop losses so it is mostly fully open or fully closed?
Or perhaps its best to develop a converging-diverging nozzle that can be deformed to provide efficient throttling functions.
@@InfinionExperiments PWM would not be a good choice, you are just averaging out the losses as the valve is not instantly open or closed at any one time. At his stage of testing it would be wise to concentrate on the efficiency of the turbine and disregard the efficiency of the system IMO.
@Jeremiah Use a step-up transformer that will improve your design
My main turbine project produces 400v ac.
When you opened the valve to the big tank, I thought it sounded like you had liquid in the tank which comes from the moisture in the air. Obviously, you did and you have to drain that out once in a while. Nevertheless, good video about a Tesla turbine.
Actually I filled the tank up half way with water and heated the water up to add hot vapor to the compressed air. Don't worry though, I regularly test the tank over 150 psi with water so that there is no danger of explosion during testing.
95000 rpm is 1583 rps X 6" x 3.14 x 0.0254 = 757m/s or 2,727Km/hour or 1,704 miles per hour. Have you calculated the efficiency of this system?
It's a 3" rotor. We are going to calculate the isentropic efficiency soon on our 6" rotor using our analytical equipment.
Nice test with humid air if you can make it run for a few hours while it is producing 500 watt that would be something 😀 i wonder what the nozzle diameter is ?
how large is your tank?
the tank is half full of water, so it's about 12 gallons of air.
❤
Doesn't the cold steam setup use less applied energy and still get the same output?
Also
Why does the load slow it down? is it the winding or use of a magnetic field causing a torque or a drag-ah what's the word? I lost my train of thought😢😂.
Not static friction..lol. just why. 😅
Great questions! The cold steam setup does use less applied energy due to the efficiency of phase change and heat transfer processes, but the actual output depends on the overall system design and losses involved.
As for the load slowing it down, you're probably thinking of 'back EMF' or 'counter torque.' When a load is applied, it creates resistance against the motion, increasing the demand for energy. This can be due to several factors, like magnetic drag, mechanical friction, or electrical resistance in the windings. All these can cause the system to slow down as it tries to maintain balance. No worries, it's a complex topic, and losing your train of thought happens to all of us! 😅
It was torture thinking of that word. I see it now right there it was torque.i had already used it. It slows it down w\o even touching it. So Kool
I'm so glad to see you after all these years having this much fun and all these successes. You go boy.
This is my little idea it’s working or not. I don’t know you need to add some flywheel. ?
For these smaller turbines, that would be a very useful way to stabilize the RPM. My main turbine project has a much larger rotor made with heavier material, which helps stabilize the RPM. Stay tuned to see this effect in action.
Steady at 30v at 7.5a with 500w load. Perty good but what gpm is it using of the air? With 200 psi in the tank looked like running..
100 psi was the max pressure in these tests. If I increased the water temperature it would run for much longer and if my generator was more powerful I could output much more power.
Have you guys tried or thought of using different fluids? Such as supercritical co2? For off grid that would be good to have backup fluid type options
Thanks
We definitely want to explore using them in the future. However, I want to avoid supercritical CO₂, as the high pressures it requires would exponentially increase the system's costs.
How are you going with the "creep" problem?
Hasn't been a problem. Just using the correct materials.
Something I have wondered with Tesla Turbines having a hard time converting their speed into torque.... is there a way to use a gear system (like a bike) that can be increased as more momentum is built to spin a series of increasingly large Flywheels or multiple of them in succession to make the motion more useful? Say even as a solar battery system, where they would get faster and more mass during the middle the day and as the solar drops off at say 4pm, then the momentum built by the flywheel could be utilized?
In my brain, this idea could also be best used in a hydro dam or on a waterfall or something.
Thanks for your comment and interesting ideas! Regarding torque, the Tesla Turbine operates at extremely high RPMs, which compensates for the lower torque with a high power output. Since power is a function of both torque and RPM, the high speed of the Tesla Turbine allows it to produce substantial power, even with lower torque. In our latest tests, we've seen excellent power output without any torque issues, especially when paired with a generator using air cores. This setup allows us to efficiently transform the high-voltage output into low-voltage, high-amp output using electronics, which suits our needs perfectly.
Now, to address your other questions:
Using a Gear System and Flywheels: Your idea of using a gear system to gradually engage larger flywheels as momentum builds is quite interesting. In principle, it could work as a form of energy storage, where excess kinetic energy is stored in the flywheels and then released when needed. This would require precise control to engage the gears without losing efficiency, and the system would need to be robust to handle the rapid changes in speed and torque.
Solar Battery System: Using this concept in a solar battery system is another intriguing application. The flywheels could store energy generated during peak solar hours and then release it gradually as solar input decreases. However, one challenge would be managing the losses inherent in mechanical systems and ensuring that the stored energy can be efficiently converted back into electrical energy when needed.
Hydro or Waterfall Application: In a hydro setting, the consistent flow of water could keep the flywheels spinning, making this a more practical application. The system could potentially act as a buffer, storing excess energy during low demand and releasing it during peak demand, similar to pumped storage but in a more compact and potentially more responsive system.
Overall, while these ideas are conceptually sound, implementing them would require careful design to minimize losses and ensure efficiency. For the Tesla Turbine specifically, our focus has been on optimizing the electrical output directly, and so far, it’s working very well with our current setup.
@@iEnergySupply 100% Yes, and it makes sense that you lose efficiency as you add additional mechanisms on to the Tesla Turbine too.
Personally, I am just shocked that the Tesla Turbine exists, and that no one has been able to find a real way to make it functional.
I am aware that current Hydro powered dams like the Hoover Dam have a +90% efficiency (which is very impressive). I wonder if there is a way to use the Tesla Turbine other than it being a psychological exercise?
It feels a bit like Da Vinci's ornithopter... beautifully drawn, interesting concept, but not useful in reality. Who knows. haha
@@iEnergySupply you know I originally thought of gears just to speed up the turbines spinning output... It's just not necessary! That thing spins fast enough, right?
Have you any efficiency tests results?
In previous tests, we estimated an isentropic efficiency of approximately 99%, though this was a rough calculation. We are planning further testing with more accurate and precise measurements. While 99% may seem high, particularly when compared to other turbines of similar size, it is important to note that the overall thermal efficiency of such cycles tends to be relatively low. However, our goal is to significantly enhance the thermal efficiency as we continue to refine the system.
Can we get a build video on your turbine?
@@donavonneighbors I might end up doing that eventually
@@iEnergySupply I actually live in Spokane. Can I just come check it out? lol 😂
@@donavonneighbors Maybe some time we will accept some visitors, I would have to get an ok with my partner. Can I get your email, if you send it delete it shortly after.
@@iEnergySupply okay it seems like you got it. Thanks for the consideration!
The last stage of Megawatt scale steam turbines experience transonic flow for the steam present.
Stirling engine fans (me) are punching the air right now, because it not a toy model and actually generates power.
Could you not set up a system that uses geothermal cooling/ solar heating and cold steam in vacuum to serve as the means to turn the turbine?
Currently, we are working on a system that utilizes a thermal reservoir to power a turbine. My latest tests focus on this approach, which allows for the thermal mass to be charged with almost any heat source to generate electricity.
@@iEnergySupply amazing!
I was thinking about the use of a heat pump as they have up to 4:1 COP.
The problem with very low temperature differentials is you are limited by the carnot efficiency, low temperature differential = low efficiency. That's a big reason we use superheated steam in large scale turbines
I’m new how you getting air?
Air compressor, but with the new 6" turbine, it's made of aluminum and has a metal rotor so to generate electricity, all you need is to heat the thermal reservoir. You can use firewood, wood chips, diesel, waste oil, gasoline, trash, or even solar thermal energy-basically, any fuel you can think of.
What are the discs made of?
@@EugeneWangombe carbon fiber in this test
@@iEnergySupply interesting, self made?
lightweight, resisting hihg rpm and being much more easy to make by hand than most metals.
what expoxy or binder did you use in the carbon fiber(or what material you used at it, not as much interested in the speciffic brand as in the speciffic types since most brands which people on the internet use aren't available here(netherlands)),
especially since many epoxies can't handle to high temperatures. similar to plastic.
@@ted_van_loon I used a fairly generic carbon fiber I found online for this build. If I could source a high-temperature-resistant carbon fiber, it would be ideal. I did find a type rated for 500°F (260°C), but after testing, it turned out to be too weak. I made disks from it and spun a 6" diameter rotor up to about 33,000 RPM, but unfortunately, the disk failed and shattered under the stress.
Interestingly, FR4 fiberglass has shown to be stronger in some of my tests, despite its limitations with temperature resistance. To avoid issues with heat and mechanical stress, I've switched to titanium for the larger 6" rotor during testing. While titanium is quite expensive, its strength and resistance to high temperatures make it an excellent material for these applications-especially when dealing with high rotational speeds and thermal challenges. It’s proven to be a real game-changer for this project.
Add plasma reduce friction potentially find a quantum vacuum with the addition of plasma
How do you propose I add the plasma?
@@iEnergySupply plasma steam systems of which I don’t know much but I know steam allows for charge separation which is a key component of the magic of plasma. There are commercially available units found in Google. Other way include spark gap this might sound crazy but could you use the housing as a cathode and turbine discs as an anode ? Another way would be to generate EVO’s a form for plasma similar to ball lightning via shear and cavitation like Kladov or Cavitation by water hammer like Bin Huang. All the info for those systems is available on the Martin Fleischmann Memorial Project on TH-cam
@@iEnergySupply I forgot to mention the reason I said plasma is that by ionizing the wings of jets aka plasma they can go ultrasonic
Weird my first reply didn’t stick. But I mentioned the work of Kladov, Bin Huang, Ken Shoulders, Matsumoto. They all in different ways created charge separation which led to the formation of EVO’s aka ball lightning. I also know that steam at certain temperatures is a state of water which generates charge separation. There are commercially available plasma steam units for many things. My favourite idea is make the housing the cathode and the discs the anode and pulsing HV AC with constant DC ! Bin Huang system uses steam recycling the water is key as the EVO’s build up and more of the magic happens. All the above mentioned is available on the Martin Fleischmann Memorial Project has a Page on TH-cam. Be sure to look through the Live Videos. Plasma is used by the military to go ultra sonic when you posted about breaking the sound barrier, I immediately thought wouldn’t that be something. Tesla was a big fan of plasma and ball lightning. Only makes sense that you make the steam plasma for his turbine
@@iEnergySupply I should mention it that a lot of these devices create strange radiation find videos regarding this on the Martin Fleischman Memorial projects page if you see any of these that you watch thosevideos on safety. Also, if you did ever pursue a system use cavitation ,implosions from cavitation are destructive precautions must be taken
Not at speed of sound in the working medium though ;-)
👍👍
Cheers!
That's interesting steam to electric. I have an idea with motor to electric generator but mine takes out the load makes it non inductive
I'd love to see it!
Dude, you don't need to show rip'ems. You can just show the hz of the power being generated. That's basically the same as showing RPM. Flip that fake Fluke from flow to Hz.
I tried, but the frequency became unstable at around 32,000 RPM. To measure the RPM, I analyzed the sound using the Spectroid app, which I’ve found to be very accurate when compared to an actual RPM meter. In this test, using an RPM meter wasn’t possible because the shaft was not exposed.
One thing I'm wondering is, since you have to use electricity to use the compressor, even if you run a tesla turbine, you still have to use external electricity, so in conclusion, you're generating electricity, but isn't it offsetting?
To generate electricity, all you need is to heat the thermal reservoir. You can use firewood, wood chips, diesel, waste oil, gasoline, trash, or even solar thermal energy-basically, any fuel you can think of. The versatility of that is truly amazing!
The compressor is only used at start up, once it gets going, you can turn off the compressor and it keeps running until all the energy from the hot tank is used up
@@PhillyEaglesFanaticYes, after you pull a vacuum on the main system, the vacuum pump doesn’t need to be turned on again unless there are leaks in the system.
Ok INsANE idea what if you inject a fuel air mixture into the turbine, have the turbine spit it out of its exhaust, then ignite the exhaust and feed it into an axial turbine. TESLA turbine Turbojet
That's on the to do list, I've started the R&D for it but have been waiting for more time to finish!
Nice 👍 away to sub and watch what else you got lol
Awesome thank you!
lol now you can boiling the kettle with enough air providing a major bearing failure doesnt occur which it will without oil feed and/cooling.
Damn it, back to the drawing board once again😂😂🤣
These bearings have withstood several rotor crashes caused by misalignment, which I've since corrected. Amazingly, I've been testing with the same bearings for over 4 years, and they’re designed to run without oil. With the alignment issues resolved, no more crashing rotors! My new 6" turbine is now bulletproof. Cheers!
Putting a steam engine on it would be the shit ... you could run it off a alcohol burner if would be a lot more quiet 🤫
our main turbine is very quiet in comparison, this is just a plastic one I built for fun! And the main turbine you can run with nearly any fuel!

You need to put a drier on the compressor. The water needs to be removed before its released
Can you explain more why you think a dryer would help?
@@iEnergySupply water can cause drag and rust etc. Especially in bearings. We use water traps on all of our air compressors in my work shop. Just thought id mention it 😎👍
Isn't that one of the benefits of the tesla turbine that you can use wet steam?
@@FilterYT absolutely!
Ooooo
How long can it sustain that output?
Not for very long with compressed air and my small tank, but we will see how it performs with the cold steam, heat reservoir, and my large turbine.
In principle you expand almost the whole pressure within the nozzle in order to make as much kinetic energy of the gas flow as possible. You only use a very small fraction of total pressure drop to drive the gas through the turbine gaps. You only need the remaining pressure drop to generate enough torque to compensate the torque of the generator and some friction losses.
I don't understand why you spiral the flow from the outer rim to the inner rim of the gaps. It doesnt make sense because it generates only much more friction than you really need. I would keep the flow at the outer rim of the gaps in order to release it after a half of the perimeter. So you have nearly constant streaming conditions and it is easy to calculate.
When you find that the outer rim of your turbine goes supersonic than you know, that you work not very efficient. The maximum speed of the gas flow, you can reach ist sound speed. If you want supesonic flow you have to use a Venturi nozzle (with diffusor). So the outer rim of your turbine is faster than the gas flow at the end of the nozzle.
It means the outer rim of the nozzle acts as a break, which ist driven by the inner gap section. This is also the reason why I don't like Tesla's turbine design, because it is simply not very efficient. You don't realize this inefficiency, because you have a lot of power in your gas flow.
Using only the outer rim of the turbine gaps is also useful to get a compact turbo generator design. You can put permanent magnet disks in the inner rotor part which operate on stator air coils in the turbo generator housing plates (4 permanent magnets and 3 coil pairs on both housing plates). In this way you will get an axial flux generator without iron losses.
Thank you for your insightful comment! You've raised some important points about the efficiency of Tesla's turbine design and the potential for supersonic flow at the outer rim.
One of the core principles behind Tesla's turbine is rooted in his understanding of fluid dynamics, particularly the importance of allowing fluids to move in natural spiral paths with minimal resistance. According to Tesla, this design helps avoid the sudden changes in velocity and direction found in more conventional turbines that rely on blades or vanes. The spiral movement of the fluid, influenced by the adhesion and viscosity properties, allows for a more gradual transfer of energy as the fluid moves toward the center of the disks. This gradual transition minimizes the losses associated with shocks and disturbances that you’d see in traditional turbines.
While your suggestion of maintaining the flow at the outer rim for constant streaming conditions is logical, Tesla’s design deliberately uses the spiral inward motion to continuously reduce the velocity of the fluid and extract as much energy as possible over the entire flow path. By the time the fluid reaches the center, it has already imparted a substantial portion of its energy to the turbine. Tesla himself noted that “the performance of such machines augments at an exceedingly high rate with the increase of their size and speed of revolution.” This suggests that while the design may seem less efficient in theory, in practice, the fluid's interaction with the entire disk surface optimizes the energy extraction process.
Regarding your observation about supersonic flow, Tesla designed the turbine with the idea that, under normal conditions, the fluid’s velocity should match the peripheral speed of the disks. When the turbine is properly scaled and tuned, the speed of the fluid and the turbine's edge should remain subsonic. Tesla acknowledged that if there’s too much velocity mismatch, inefficiencies can arise, but he accounted for this by recommending increased disk area or reduced spacing, depending on the fluid properties.
@@iEnergySupply hm, when you design a turbine which spirals the flow from the outer rim to the inner rim of a spacing between disks you accelerate the flow from the outer rim to the inner rim because you decrease the static pressure in order to transfer it into dynamic pressure.
But along the path the transversal velocity of the disk is decreased. This means the difference between the gas velocity and the transversal disk velocity gets higher and higher. This means the friction becomes higher and higher.
At the end of the process you will get a very stange equilibrium where you generate a lot of friction and your gas tends to return to the outer rim of the disk space but the static pressure in the outer gas spirals acts in a way to suppress this tendency.
I cannot imagine that this equilibrium state is somehow characterized by a good transfer rate of kinetic energy from the gas to the disk.
In my experiments I have found that the best efficiency comes with relatively constant but slidely increasing gas velocity, where the velocity difference between gas and disk is more or less constant and small enough that you don't waste too much energy into gas friction.
In a bladeless turbine you need some dissipative friction in order to transfer the torque. But you just need the torque to drive your high speed generator, which is relatively small. You generate your mechanical and electric power in turbine engines mainly with your angular velocity and not with your torque.
P = 2*pi*f*T
P: mechanical power [W]
f: frequency of rotation [1/s]
T: torque [Nm]
So, the best you can do is to keep the gas at the outer rim of your disk space and to keep the gas velocity constant and slidely higher than the disk's transversal velocity. Only in this way you loose the smalles amount of power due to friction. So the most power ist transferred to the disk.
With an inward spiral you can probably get more torque but you lose a lot of power due to friction. This is probably also the reason why your rotor immediately accelerates very hard. But this is not the way to make an efficient turbine.
A turbine lives from the gas speed and not from the gas friction. A turbine accelerates smoothly to its nominal speed.
Only dental turbines are designed to generate a lot of torque at lower speed. But they are not optimized for higher efficiencies. These turbines are not active but reactive turbines Their blades stand like a wall in the gas flow like in a mixture of a pelton turbine and a rotary vane pump. They are mainly (stagnation) pressure driven engines and act more like piston engines.
@@gkdresden The phenomenon you described is something I generally agree with in terms of fluid dynamics and turbine efficiency. However, in the case of the video you're referring to, the reason the turbine didn’t start immediately was actually something I hadn't seen before. Upon inspection, I found that the rotor wasn’t properly aligned and was making contact with the side wall. This misalignment caused the rotor to scrape the side wall, and I had to overcome the friction of this contact before the turbine could start.
This aligns with the broader point you made about friction, but in this case, it was an unintended mechanical issue rather than a design characteristic of the turbine.
Additionally, as you mentioned regarding the transfer of energy, it's important to note that by ensuring proper construction and observing working conditions, the centrifugal pressure opposing the fluid's passage can be made nearly equal to the supply pressure when the turbine is running idle. If the inlet section is sufficiently large, even small variations in rotational speed can result in significant differences in flow. This effect is further amplified by the changes in the spiral path length, creating a self-regulating machine. This concept bears a resemblance to a direct-current electric motor, where significant differences in impressed pressure are counteracted by the rotation, preventing excessive fluid flow.
It's also worth noting that due to the laminar flow within the turbine, this self-regulating behavior becomes possible. The fluid passage through the turbine can remain highly efficient, as the system only uses as much flow as required for a particular load. This ensures that the turbine's efficiency remains high while minimizing unnecessary flow, further optimizing performance under varying conditions.
In the case of my turbine, this issue was compounded by the friction caused by the rotor's misalignment, but your point on efficiency is well taken.
actually while partly true and seemingly true, it is actually not fully true, that is because the tesla turbine's working is actually far more complex and advanced than it seems, but 99.99% of science and even the people explaining them and such do not properly understand the engine.
several years ago when I made my first 3d printed tesla turbine I noticed some odd behaviour and using that managed to figure out it's actual working.
this is also backed by how nikola tesla was great in geometry optimizations, yet somehow speciffically said the room needed to be round, and also didn't say you needed a special nozzle. essentially I rediscovered the way the tesla turbine was actually meant to work, and did some reseach and a more complex advanced version of simulations on it(actually the same type of simulation nikola tesla used to test his mashines which up to today still is much more accurate and faster than computer simulation programs).
but the interesting things I found where :
1: you don't need a nozzle since the tesla turbine generates a relative aerospike, this is similar to that new technology in rocket engines, but it already was there around 100 year ago in the tesla turbine, the aerospike in the tesla turbine however automatically dynamically adjusts itself and also acts as a nozzle.
2: the tesla turbine relative adaptive aerospike nozzle not only extends at the inlet but through the entire device, forming a adaping dynaming converging divergent nozzle, which actually is a type of nozzle used in rockets to make them go faster than sound, but in rockets they are fixed so only efficient at a very speciffic speed, while in the tesla turbine it is much more powerfull.
essentially in most cases adding a nozzle or such will decrease efficiency.
and a tesla turbine can go faster than sound on it's own while remaining efficient.
that said when going much faster than sound you start to run in other ineficiencies no mather what turbine you use.
@@ted_van_loon It’s great to hear from someone who’s done such thorough research! I’ve long suspected that the divergent section of the nozzle isn’t necessary within the nozzle itself, and your findings about the adaptive aerospike behavior of the Tesla turbine validate that. The way the turbine’s spiral flow through the disk gaps naturally acts as the divergent section makes perfect sense, essentially allowing supersonic flow without the need for a traditional nozzle.
The idea of the turbine dynamically adjusting its flow path and essentially forming a converging-diverging nozzle throughout the entire device is brilliant. It truly reflects Tesla’s genius in optimizing geometry-something that’s still not fully understood by most modern explanations. The fact that the turbine can generate and adjust its own aerospike shows how advanced the internal fluid dynamics really are. I don’t think most people, or even modern simulations, fully grasp how intricate this system is.
I also agree that adding a nozzle can reduce efficiency in many cases. The Tesla turbine is inherently more powerful when left to its own dynamic flow adjustments. It’s remarkable that this technology can achieve supersonic speeds while maintaining efficiency, unlike fixed-nozzle systems. But as you pointed out, even when the turbine exceeds certain supersonic thresholds, some inefficiencies start to appear-this seems to be an unavoidable limitation for any turbine at extremely high velocities.
It’s exciting to think that Tesla had already figured this out over a century ago, and how much more efficient his approach was compared to many modern systems. I’d love to see more people dive deeper into these core principles-understanding them could truly revolutionize how we apply this technology today!
I do have a question for you, though: when I run my turbine in a vacuum and get the rotor spinning close to the speed of sound, if I turn off the gas inlet, the rotor maintains its speed for a long time due to the low atmospheric pressure. I’m wondering, based on what Tesla described about using pulses of gas as the most efficient way to run the turbine, could this approach reduce the negative effects of running the turbine at such high velocities in a vacuum? Perhaps the low pressure environment could make the pulsed gas more effective by minimizing turbulence or drag? I'd be curious to hear your thoughts on this.
Vidéo intéressante, mais le principe de fonctionnement n est pas expliqué. Construire cette machine est intéressant mais y a t il des applications industrielles ( commerciales) pour créer de l électricité à prix faible? Sinon quel est l intérêt d avoir construit cette machine? Est ce une machine rentable ? Une 2ème vidéo plus détaillée et expliquée serait la bienvenue.
Геотермальные станции работают примерно по такому же принципу.
Merci pour votre commentaire ! J'apprécie votre intérêt. Le principe de fonctionnement de la turbine Tesla repose sur la friction de la couche limite, où le fluide se déplace en spirale entre des disques étroitement espacés, transférant ainsi de l'énergie aux disques sans avoir besoin de pales traditionnelles.
En ce qui concerne les applications industrielles ou commerciales, bien que les turbines Tesla ne soient pas largement utilisées aujourd'hui dans la production d'énergie à grande échelle, elles ont un potentiel dans des domaines spécifiques, comme la récupération de chaleur perdue, la production d'électricité à petite échelle, et la production d'énergie à faible coût à partir de sources renouvelables comme la géothermie ou le solaire thermique. La simplicité de leur conception pourrait entraîner des coûts de maintenance plus bas par rapport aux turbines traditionnelles, même s'il reste encore des défis techniques à relever pour une utilisation à grande échelle.
Je suis d'accord qu'une explication plus détaillée serait utile. Je prévois de réaliser une vidéo de suivi où j'expliquerai en profondeur les principes et les applications potentielles dans le monde réel. Restez à l'écoute !
Try to get in Touch with Peter Lindeman and Aaron Murakami,
they will tell you that tesla intended his turbine to work in sister conjunction with another as a 99.9% heat->motion konverter using "cold" steam.
nonetheless nice work keep it up
I work in Aaron's shop, haha. Achieving 99.9% conversion of heat would be the ultimate dream. I hope it happens one day, but it's a very difficult feat of engineering.

What's a terubine?
A terubine is a highly sophisticated machine that generates power using nothing but typos and awkward moments. Sadly, I haven’t perfected it yet... still working on spelling 😂
Naw that's just the Japanese pronunciation!❤
What is it really good for, its to noisy to power your house for one !
Our 6" rotor in the vacuum is very quiet in compared to this one, and you wouldn't want it in your living room! haha
@@iEnergySupply Только не тогда, когда к вам в очередной раз нагрянут надоевшие соседи, вот тогда работа двигателя будет неоценима :D
@@SINHRO-FAZA Это забавно - мой самый тихий турбина был настолько бесшумным, что люди думали, что он фейковый! Они спрашивали: 'Почему его не слышно?', потому что они привыкли к очень громким турбинам.
Its not the velocity thats important, its volumetric flow. Velocity comes along for the ride.
Speed is actually more crucial than most people realize when it comes to the Tesla turbine. If done properly, it can become a self-regulating machine-kind of like a DC motor. Even if the pressure changes a lot, the rotation controls the fluid flow. What's cool is that the centrifugal force increases with the square of the rotational speed (or even faster in some cases), so higher speeds really make a huge difference.
With modern high-grade steel allowing for crazy high peripheral velocities, it's possible to reach that self-regulating state in just a single stage, especially with a larger diameter runner. So yeah, speed is a major factor here, more than it might seem at first!
This is insane. The super contra rat army of Contrarium.. Who opened the cage? These creatures are everywhere!
@@CoincidenceTheorist A lot of armchair generals these days, dont worry about it too much, they're needed for algorithm engagement.
You need a dryer the expanding air is droping temps causing condensation.
Or we could just increase the temperature, which isn’t too bad for a laminar flow turbine. However, I’m curious to see how a dryer would perform in this setup.
That seems fairly inefficient. The 500W extracted from the turbine compared with the couple kW to go into supplying the air to make that 500W.
Running the generator at high frequency is potentially problematic depending on the rectifier. The 1500Hz isn't really fast but the high current rectifier might be quite slow.
The relatively low voltage of 50V is also quite lossy if you're using a silicon diode rectifier. It'll have 1.4-2.0V across it depending on it's specs and the current. This means that you're losing about something like 4% of the energy just in rectifier losses.
You can get a frequency measurement in real time quite easily if you use 1 of the 2 meters on the Hz range.
I suspect you actually know the energy efficiency is about energi in vs energy out, not power in vs power out. Still, one small Tesla turbine can't be very efficient. Your point about losses in rectifying the voltage is valid, if it the voltage is rectified, which isn't necessary to run incandescent lights.
They can redesign the generator to increase the voltage. They're experimenting, not showing a finished product for sale. Also, ~4% additional loss in rectifying isn't much in that context. Consider the videos as entertainment.
BTW nice to see that you use the proper unit symbols, I think the convention is leaving a space between the number and the symbol in common text, but hey, just using the right symbols is rare in youtube comments.
Thanks for the detailed input! You’re right; there are efficiency challenges when matching the input power to the output. The goal of this setup was to demonstrate the concept and the potential of using various heat sources to drive the turbine. I’m currently focused on optimizing the entire system, including the generator and rectification stages, to reduce losses.
For the main project, I’m working on a larger turbine paired with a coreless generator that outputs 400V. With this higher voltage, the rectifier losses should be much lower, making the system more efficient. I’m also considering using more advanced rectification methods, like Schottky diodes or MOSFETs, to further reduce voltage drops and improve overall performance.
It won't work
Already tested it, and it works.
Bruhhh what kind of shit are you on? What do you mean it won't work? Have you seen any of his videos? Are you just a deep state shill or bot?
@@PhillyEaglesFanatic hahah love the comment!
I woukd take a piston drive with high torque any day. So much lost energy here
You haven’t seen my latest progress on the large turbine. You can also convert torque from a generator to a motor to get as much torque as you need. However, comparing the two isn’t really relevant because the turbine serves a completely different purpose than a piston engine for what I am doing.
You're impressed with high-speed machinery? You should get out more.
Your not impressed with high speed machinery?
With the right construction and conditions, the centrifugal pressure can almost match the supply pressure when the machine is idling. If the inlet is large, small changes in speed can cause big differences in fluid flow, helped by changes in the spiral path length. This creates a self-regulating machine, similar to a DC motor, where fluid flow is restricted by rotation, even with big pressure differences. Since centrifugal force increases with the square of speed, and modern steel allows for high velocities, this can be achieved in a single-stage machine, especially with a large runner.
@@iEnergySupplythis guy has to be some sort of boł. Theres so much non human interaction in comments now. Its quite disturbing
I didn't hear any sonic boom! Nothing went supersonic without a sonic boom, even a whip has a sonic boom as it breaks the speed of sound!
Yes, it's interesting. The laminar flow in the Tesla turbine might be the reason, but it definitely reached the speed of sound.
@@iEnergySupply not without that boom it didn't!
@@timh.2137 fffs, it isnt even worth explaining... but i will anyway, though i get the impression you wont understand, or want to understand. if the air is supersonic, and the blade moving within that air is also supersonic, it doesnt produce a "boom" because the relative speed between the two is NOT supersonic.
anyway, a "boom" is a single wavefront, a single rapid rise of pressure, moving past you. not a continuous sustained note.
when a propellor tip exceeds SoS, theres also no "sonic boom", but it does make an awful "tearing" sound... very distinctive.
fun fact, air exiting a nozzle at anything over 16 or so psi is already travelling at sonic speeds...
whats a "terubine"?
did you even take the time to look at the thumbnail before posting?
you dont know what a terubine is?
The terubine is a turbine with a 1000x more bines than a gigubine, and a 1,000,000x more bines than a megubine. That's why he lowered the pressure. The tur/bine ratio is way off and you have to lower the speed to get the right ratio.
@@ClericChris then what the hell is a concubine?!?!?!?!
lol, that gave me a much needed laugh... :)
A Terubine is a vicious predator closely related to the Tasmanian devil.
My dyslexia got the better of me ahaha Sorry!

Sometimes I get in a hurry, haha. It happens! Even though I know how to spell 'turbine,' spelling isn’t always my strong suit.

Nothing weird has happened so far-no gremlins. I did have a turbine stolen once, though, from my car. I turned my head for a moment while talking with my dad, and it was gone. Someone knew exactly what they wanted, and I have no idea how they even knew it was in my car.
